GAS, HEATER.

Application filed February 8, 1923. Serial No. 617,792.

My invention relatesto in'iproven'ients in gas heaters,and more particularly has reference to a portable circular type of heater of artistic design, which maybe conveniently assembled or taken apart, and may be conveniently shifted when desired.

In the accompanying drawings, I have illustrated in Fig. 1 in front elevation, a heater embodying an application of my invention, partsbeing broken away. Fig. 2 is a section looking from right to left on the line 22 of F ig. 1. Fig. 3 is a plan view looking down upon the upper part of the'burner. Fig. i is a front view of the burner. Fig. 5 a view Fig.6 a longitudinal section of the burner. Fig.7 a crosssection on the line 77 of Fig. 6. Fig. 8 is a front elevation on a reduced scale of the radiant. Fig. 9 is a section on the line 9-9 of F ig. 8. Fig. 10 is a section on the line 1010 of Fig. 8. Fig. 11 is a cross-section of part of the grill looking from right to left at the same when mounted in the heater.

12indicates a suit-able form ofstandard terminating in a rectangular portion 13 at the top which is open at the back as indicated at 14. Said standard is provided with suitable flanges such as 15 which serve to support the metallic ring or frame 16 and which maybe secured thereto by any suitable means such as the screws 1? as shown. The base of the ring is looped up in U-shaped formation as indicated at 18 to provide clearance for the burner 19, saidburner being illustrated to better advantage in Figs. 3 to 7 inclusive, and being secured in the ring or frame .16 by flanges with screws such as 20. The burner the circle of the heater and is provided with a grid comprising two sections 21, 22, said sectionsbeing heldtogether by any suitable means such as the screws 23 24; indicates a sheet metal piece adapted to engage the groove 25 thus closing the bottom of the burner and forming a housing within which the air and gas mixes prior to combustion. The tubular part 19 of the burner terminates at the back adjacent the inlet plug 26 through which the gas passes from the coupling 27 upon which a flexible tube may be secured, and 28 indicates a three-legged spider attached to the framework of the heater as shown for supporting the coupling 27 and tip 26.

29 indicates a radiant of suitable refractory material which is corrugated on the front face as shown, the depth of the corrugations such as 30 being greater at the top than at the bottom, thereby increasing the area of radiant in the path of the flame as the top of thesame is approached,and the said radiant is prefeu ably 'cut away at the top as indicated at 31 to allow for escape for the products of combustion. The back of the radiant is also preferably provided with ribs or enlargements such.

as 31, thereby leaving-an air space between the radiant and the next refractory heat insulating slab such as 32 which also preferably provided with similar enlargements or ribs providing air space betweenit and the high temperature insulating slab or block 33 through which achannel 34; is also cutat the top comn'iunicating with the channel 31 in the radiant and providing for ventilation, the top of the frame 16 beingalso cut away over the channel 34 for the escape of the gases as indicated at 35.

36 is another metallic ring or band with a flange 37 at the back within whichma 1 be retained the metal disc 88 thereby closing the back of the heater, screws or bolts vsuch as 89 serving to retain said band to the ring16. 40 indicates anescutcheonor plate with an opening through which the products of combustion passout; a1 indicates thegrill of'fire clay or other suitable material throughwhich the radiant is exposed and said grill is ret'ainedagainst the ring 16 byanysuitable n'ieans such as the cleats 42 which may :be

turned upon screws or pins 43. At. the front of the heater a frame "or'ringl l maybe secured by any suitable means such as screws -15 which pass through the tube or bushing 46 between the framets and ring 16 and into the frame 16, as shown to better advantage in 16 indicates a circular fiange around the upper part of the front of the radiant 29 adapted to fit within the flange 47 of the ring 16.

Of course it will be understood that various modifications may be made in the construction and arrangen'ient ofparts without departing from the spirit of the invention as claimed.

I claim: 1. In a heater of the class described, a heat radiating element substantially circular upon ill) its horizontal axis, a burner adjacent the lower front of said element, said burner at its outlet curved substantially in conformity with the'curvature of said element. 7 g p 2. In a heater of the class described, a heat radiating element substantially circular upon its horizontal axis, a burner adjacent the lower front of said element, said burner adapted to discharge a greater quantity of .gas as the center thereof is approached from its opposite ends.

3. In a heater of the class described, a heat radiating element substantially circular upon its horizontal axis, a burner adjacent the lower front of said element, said burner partly circular upon its horizontal axis andadapted to produce a flame havingauupper edge representing" a curve of greater radius than the curve of said burner.

4t. In a heater of the class described, a heat radiating element substantially circular upon its horizontal axis, a burner adjacent the lower front of said element, said burner at its out;

let curved substantially in conformity with the curvature of said element and a substantially circular grill in front of said element and burner.

5. In a heater of the class described, a' heat radiating element substantially circular upon its horizontal axis, a burner adjacent the lower front of said element, said burner at its outlet curved substantially in conformity with the curvature of said element and a substantially circular grill in front of said element and burner and a housing around said element and grill.

6. In a heater of the class described, a heat radiant and an insulator behind the same, and in combination therewith another insulator behind said first mentioned insulator but having lower heat vconductivity.

7. In a heater of the classdescribed, a heat radiating element substantially circular upon its horizontal axis, a burner adjacent the lower front of said element, saidburner at its outlet curved substantially in conformity with the curvature of said element, and a frame around said element. I r

8. Ina heater of the class described, a heat radiating element substantially circular upon its horizontal axis, a burner adjacent the lower front of said element, said burner at its outlet curved substantially in conformity with the curvature of said element, and a grill in front of said element and said burner.

9. In a heater of the class described, a substantially circular heat radiating element, grill, and insulator, and a burner adjacent the lower portionthereof and between said element and grill, a face member in front thereof, and a burner betwen said grill and radiant,

said burner removable when said face member has been removed.

'10. In a heater of the class described, a circular outer framework, a curved burner at the front and at the base of the same, a radiant immediately behind said burner and heat insulatingmaterial back of said radiant, said radiant having vertical corrugations deeper at the top than at the bottom.-

11. In a heater of the class described, a circular outer framework, a curved burner at the front and at the base of the same, a radiant immediately behind said burner and heat in sulating material back of said radiant, said radiant having vertical corrugations deeper at the top than at thebottom, and an air space between said radiant and said heat insulating cular outer framework, a curved burner at the front and at the base of .the same, a radiant immediately behind said burner and heat in sulating material back of said radiant, said radiant having Verticalcorrugations deeper at the-top than at the bottom, and an air space between said radiant and said heat insulating material, and means for supplying gas at the back of said heater, said heater having a standard inunediately beneath the centre of said burner. j
